WMF Function 4 vegetable steamer 20 cm (7.9 in) review
A fixed 20 cm (7.9 in) insert in uncoated Cromargan, 11 cm (4.3 in) deep, stated oven safe to 250 °C (482 °F) and designed to match WMF’s own 20 cm (7.9 in) pots.
What we would actually buy A proper insert rather than a folding compromise. The price is the price of it being rigid and deep.
What you are getting
A fixed 20 cm (7.9 in) insert in uncoated Cromargan 18/10, 11 cm (4.3 in) deep, stated oven safe to 250 °C (482 °F), designed to match WMF’s Function 4 20 cm (7.9 in) pots.
Depth
Eleven centimeters. A folding basket holds a single layer; this holds a meal’s worth. If steaming is something you do weekly rather than occasionally, that is the difference.
The oven figure
250 °C (482 °F), published. It means the insert can be used as a rack or a strainer in an oven as well as a steamer on the hob, which no folding basket offers.
The fit
Matched to WMF’s own 20 cm (7.9 in) pots. It will sit in many others; the rim design is what it was made for, so measure your pot’s inside diameter before ordering.
Availability
On sale at around $120 on the American Amazon store at the time of checking.

Fixed and rigid, so it does not collapse when full

The questions that come in
Will it fit a non-WMF pot?
WMF states it is for their Function 4 20 cm (7.9 in) pots. A 20 cm (7.9 in) insert will sit in many 20 cm (7.9 in) pots, but the fit is designed around a specific rim — measure before ordering.
Why is depth worth paying for?
A folding basket holds one layer of florets. An 11 cm (4.3 in) insert holds enough vegetables for four, which is the difference between steaming as a habit and steaming as an occasion.
Our score
8.7/ 10
A proper insert rather than a folding compromise. The price is the price of it being rigid and deep.
What use this one answers, among cookware and knives
A WMF kitchen, or anyone with a 20 cm (7.9 in) pot who steams often.

Folds from 14 to 23 cm (5.5 to 9.1 in) · 430 stainless · three feet · petal design · compact storage
A folding petal basket that spans 14 to 23 cm (5.5 to 9.1 in), so it fits nearly any pot in a domestic kitchen, with three feet to hold food clear of the water.
Ø 17.5 cm (6.9 in) · 304 stainless · fixed basket with a handle · also a colander · perforated base
A fixed 17.5 cm (6.9 in) basket in 304 stainless with a handle, which makes it a steamer that can be lifted out hot — and a colander the rest of the time.
Best for: A pot you own and use often, where a fixed basket beats an adjustable one.
